IEEE (2005) ST4B Model This model is a variation of the Type ST3A model, with a proportional plus integral (PI) regulator block replacing the lag-lead regulator characteristic that was in the ST3A model. Both potential- and compoundsource rectifier excitation systems are modeled. The PI regulator blocks have nonwindup limits that are represented. The voltage regulator of this model is typically implemented digitally.
